Here’s another Sampler for iOS with an innovative and interesting interface called SpheroSampler. Working a track? Try sampling a part of it into this and record your mutations back into your arrangement during a break. That’s one idea for SpheroSampler. It’s free.

“Use your fingers to vary speed and rotation of spheres to create and listen sphero-tracks. There are infinite number of ways to play each your sphero-track, because you have not one, but two dimensions for playing! SpheroSampler can write sounds via microphone, and also has built-in synth. Sphero-tracks can be saved (up to 8 tracks for each sphere). Live mixes can be exported into wav-files (up to 120 sec of recording).” – spherosampler.com
